The best time to visit the Scottish Highlands is from June to August. Summer temperatures are best for exploring the Highlands, however, with Scotland's location so far up north on the globe, don't expect a traditionally hot summer. During the country's warmest month (August), highs rarely surpass the 70-degree mark.

The Highlands’ summer presents long daylight hours with mild temperatures between 12°C and 18°C. June to August is ideal for hiking and exploring due to extended daylight. Rainfall is common but usually lighter than other seasons. Days can extend up to 18 hours, allowing ample time for outdoor activities.
